There are not too many things a STIHL YARD BOSS® can't handle.

MM Weight Kit is rated 2.5 out of 5 by 2.

Rated 4 out of 5 by Jtbaily5 from GreatNot sure why other reviewer has problems? This is so simple and works well. Goes on when I do first till of season and cones off to maintain through season. Easy on and easy off in 2 minutes. Never cones loose and does exactly what it was designed to do. Great help in packed soil.

Rated 1 out of 5 by RAM51 from It is essential for the Yard Boss but has issuesI have a STIHL Yard Boss that is approx. three years old and I have used it many times and it is a tough little machine. However, the weight kit which is essential for tilling hard compacted soil has major issues. It vibrates off every approx. 20 minutes of use. I have been re-installing it multi times and now the thread on the one side is so stripped that I can no longer use it. I feel the design is very odd to begin with along with the stem that connects the two weights is to short. I have several STIHL products and think very highly of their products but this weight kit leaves me scratching my head and I am disappointed to say the least with it.
